Abstract: Volume II/19 Molecular Constants mostly from Microwave, Molecular Beam and Sub-Doppler Laser Spectroscopy is a supplement to the earlier volumes II/4, II/6, and II/14. The slight change in the title reflects current trends in the applications of spectroscopic methods. Together, the four volumes collect all the critically evaluated data published up to 1989/90 on constants of free molecules obtained by classical and modern spectroscopy. Volume II/19 is divided into four parts to record the growing number of investigations, especially in the microwave and millimeter wave regions, where modern techniques like Fourier Transform Microwave Spectroscopy have made new objects of interest such as molecular complexes and clusters accessible to study. Subvolume II/19b contains corresponding data on diamagnetic asymmetric top molecules.

Subvolume II/19c contains tables for diamagnetic molecules giving further spectroscopic parameters: quadrupole coupling constants, potential barriers, and data from Stark and Zeeman effect measurements.

Abstract: The data compiled refer to susceptibility measurements (susceptibility, Curie-constants, magnetic moments, transition temperatures) and ESR-measurements (g-factors and other parameters of the applied spin Hamiltonian). In volume II/2 the literature from 1899 up to 1964 has been considered. Volume II/8 supplements volume II/2, taking into account the data on magnetic susceptibilities and ESR parameters published in the p eriod 1964 to 1968. The following subvolumes II/10,II/11, II/12 supplement data up to 1974.

Abstract: Volume II/25 is a supplemented and revised edition of the preceding volumes II/7, II/15, II/21 and II/23 containing up to date information on inorganic and organic polyatomic molecules. All experimental methods for the determination of quantitative structural data of free molecules have been considered: microwave, infrared, Raman, electronic and photoelectron spectroscopy as well as electron diffraction. The data obtained by these methods have been critically evaluated and compiled. They are presented separately for each molecule, together with a schematic figure of the structure and the original literature.

Abstract: This Landolt-Börnstein volume III/47 is a supplement to the volumes III/38 A/B "Optical Constants" and provides refractive index data published in the years 1995-2006. Included in this volume are refractive indices of inorganic, organometallic, organononmetallic, and organic liquids as well as their binary liquid mixtures at different wavelengths, temperatures, and pressures. Not all published data could be included in the printed version, but the electronic version contains all available data and references.

Abstract: This volume is a compilation of vapor–liquid equilibrium data on subcritical binary single-phase or two-phase liquid–liquid systems. All the components are well-defined pure substances, which are organic or inorganic nonelectrolytes, including low-melting ionic liquids and water. The present database contains numerical data for 3316 systems. The book reproduces in tables and graphs the numerical values for only 802 binary mixtures, chosen to be representative of all the compound classes and property types. The full set of data is given on the CD–ROM accompanying the book. Most data files contain experimental data compiled from the original literature published from 1929 to mid 2006. The CD-ROM displays all these data in PDF format and in fully documented computer readable standard electronic files (SELF and ELDATA). The ELBT-program allows the fast search of data according to property type, chemical system, author(s), source and year of publication. It also includes the bibliographical database of ELDATA, EVLM’2006, giving 13471 references from 1888 through mid 2006 to experimental vapor–liquid equilibrium in mixtures and solution.

Abstract: Diffusion – defined as mass, amount, or particle transport process – is the most essential transport property besides viscosity and thermal conductivity. Diffusion is widely used in nature, technical and scientific applications, ranging from diffusion in all kinds of gases, liquids, solids, electrolytes and their mixtures. Due to the large amount of data, the volume LB IV/15 "Diffusion in Gases, Liquids, and Electrolytes" is divided into three subvolumes. Part A: Gases in Gases, Liquids and their Mixtures; Part B: Liquids in Liquids and Liquid Mixtures; Part C: Ions and Electrolytes in Liquids, Electrolytes and Molten Salts. The presented subvolume A includes the main chapters Measurement Methods, Diffusion in Pure Gases, Diffusion in Gaseous Mixtures, Diffusion of Gas/Vapor in Gases or Liquids and Diffusion of Gases in Solution. Due to the very different and widespread measurement methods, a precise description of these methods is given.

Abstract: This critical compilation of virial coefficients of pure gases was prepared from the virial coefficient database at the Thermodynamics Research Center, formerly at Texas A&M University, College Station, Texas and now located at the National Institute of Standards and Technology, Boulder, Colorado. The virial coefficient data in this compilation will be of interest to the theoretical chemist as it includes the many sets of accurate gas imperfection data which have been determined over the past twenty years by improved methods of gas density determination, by isochoric Burnett coupling methods and from speed of sound measurements, as well as by the more traditional techniques.

Abstract: Critically evaluated experimental data covering the densities of organic compounds are essential for both scientific and industrial applications. Knowledge of densities is important in many areas, including custody transfer of materials, product specification, development of various predictive methods, and for characterizing compounds and estimating their purity. This volume contains tables with the original literature data along with their estimated uncertainties and the evaluated data in both numerical form and as coefficients to equations with selected statistical information. When data cover a sufficient temperature range, graphical plots of the deviations of the experimental data from the recommended equation are given. A Chemical Name Index contains the IUPAC names for the compounds, as well as alternate names that often appear in practice. Also includes a Chemical Abstracts Service Registry Number Index and a list of References.
